Head gasket blown 2.7l

What is your exact motor? Would mine be the ones with a distributor?

 

Toyota made 3 versions of the 3rz 2.7L 4 cylinder motor. The first one that you have is the distributor version. Outside of the USA they used this motor alot, especially in heavy equipment industry (because the distributor version came with a carburetor intake and used on foreign forklifts ALOT) this motor was used from 95.5-97 in America. The second version is the version I have which is the "wasted spark" or twin coil pack version, which is what I have, they were used in America Toyotas from 98 to 00. The final version is the coil on plug type, which is four separate coil packs for each cylinder. This version is from 01-04 in America. Technically they changed again from 03-04 but that's only in reference to the "attachments" like the throttle body and getting rid of the physical throttle cable. However the long block of the motor is exactly the same from 01-04

 

So as long as I get the one with the distributer everything should line up? I heard about maybe the egr being a problem cause the exhaust is different or do I use my original exhaust

 

Yes so long as you buy a JDM motor with a distributor you'll be safe. American EGR may not be the same so the safest option is to remove everything that isn't apart of the engine (like EGR, exhaust piping, intake piping, power steering, etc) from your motor and install it on the replacement motor.


The sensors between the 3 versions may be the same but the pin outs are different between the 3 versions, so make sure you swap everything over from your engine to the new one and you will not have any issues

 

Yes I’m gonna swap everything over from original to jdm as exhaust, egr intake etc. I’m just worried something may not bolt up to the jdm motor

 

No the castings are the same, from Japan to South America to the good ol US of A, all your stuff will bolt up the same.

 

Cool it’s been a rough month first distributor stop working had it replaced then a mechanized blew my ecm had to do that myself

 

I know the feeling. When I rebuilt my motor I thought I only needed to do the head gasket. Tearing into it I learned the head was cracked and needed a new head. After starting that I learned the oil pump got starved and needed new timing cover ... by the end of it I had to get the cylinders bored and the crank returned

Then rebuild my transmission.. so all that is rebuilt and the driveshaft rebuilt (cause the ujoints were showing their 250k age) now I'm rebuilding my suspension and steering.


These repairs will go as deep as you let them. Most important thing to keep in mind is you're driving an almost 25yr old truck. Shit wears out, but if it last that long already, imagine how long it will last when it's all new again for you! ..... at least that's what I tell myself as I slowly rebuild everything worn out on this truck

 

lmao I get yuh ima check out jdm motors but still how will the egr hook up from the old motor to new? Don’t think it would match? Also will sensors be different ?

 

Why is the 3rz from Japan look way different then the American one?

 

Because they are built for different emission control systems. And they may have different accessories, too.

 

Hence why you just pull everything off your motor and install in on the jap version

 

A dizzy is slang for distributor.

I haven't ever bought a JDM motor, but the reputation is good.

 

Also, the Japanese cars are RHD, which changes some things under the hood. the steering column is on the right, and it may cause different interferences.

 

All the more reason why you pull everything off your American speced engine and install it on the JDM version you buy.



That's the point I keep trying to make

 

I’m trying to understand lmao. So the main thing I’m doing is taking everything off the original motor and putting it same position on the jdm. Nothing more right?

 

Correct. Here is a stolen picture from yotashop.com website that is a reputable shop in my area.


This is what is referenced as a "longblock"
Notice how many auxiliary components are missing? The engine you might receive from a JDM supplier possibly will have more things attached to it. My recommendation for you in your shoes, EXCLUDING VALVE COVER (keep the JDM valve cover on) is strip it down to what is attached in this picture, and EVERYTHING extra from your current engine over to the JDM engine (if you're going that route)




If you bring ALL OF THE ACCESSORIES over from you current engine, you should be confident the electronics will match up. So make sure you swap sensors and anything electrical+all the stuff on the front and you'll be okay

 

Well if I’m swapping accessories over I kind of half to do all not half. It’s either use their harness for my harness. Is the sensors gonna be different or just the clips going to the sensor?

 

If you use your own sensors it won't matter. Your harness = your sensors


I assure you that your sensors will screw into the same hole their sensor came out of

 

So even sensors and clips should go together.
